OIL GAS GENERATOR Application filed February 2, 1931. Serial No.512,897.

This invention relates to an oil gas generator for generating oil gasfrom hydrocarbon oils by causing same to react with steam, under heatinfluence.

The mixture of the oil and steam is heated to a high temperature bymeans of moving heating elements with which the oil and steam arebrought into actual contact in the form of .a mixed spray or atomizedvapor, said heating elements being in motion in a heated gas-makinggenerator.

The heat the generator is used to flash water into steam in its passagethrough a heating grid placed inside the generator. The oil and steamare projected into direct contact with the moving heating elements, as amixed spray of oil and steam preferably by means of a cam-operated,intermittentlytimed, single-acting differential plunger pump. This pumpis timed to project the oil and steam onto the moving heating elementsat a predetermined point in the movement of the heating elements thussynchronizing the joint contact of the mixed spray v. or" oil and steam,and the heating elements.

The smaller diameter plunger of this differential pump forcing thehydrocarbon intermittently in a regulated quantity through an adjustableorifice nozzle, so constructed that the spray or jet from this nozzlewill be spread over the entire coincidently-presented surface of theheating element, when said heating or resistance element is in anincandescent state.

While electric heating elements are shown in this application theapplicant does not wish to confine himself to electric heating only asother means can be used for providing the heat.

The larger diameter plunger of the differ ential pump will deliver waterintermittently in a regulated quantity to the heating grid, inside thegenerator, from which grid it issues in the form of steam in multiplejets into the path or": the oil spray to be combined with same andprojected on to the heating element, as a mixture of oil and steam.

An object of this invention is to intermittently deliver a regulatedquantity of water into an elon ated heatin rid in a heated gas-makinggenerator, the water being flashed into steam during its passage throughthe grid, each intermittent delivery of water into one end'of the heatig grid causing a corresponding puff of steam to be discharged in jetsfrom the other end of the grid.

Another object of this invention is to intermittently deliver aregulated quantity of hydrocarbon oil into the gas-making generatorandto cause the oil to pass through an atomizer nozzle and to project intothe generator in the form of a mistlike spray.

Another object of this invention is to provide means for synchronizingthe delivery of the relatively proportioned quantities of hydrocarbonspray and the jets of steam, and to cause the projected oil spray andthe jets of steam to meet and commingle and form a mixed spray of oiland steam.

Another object of this invention is to cause the mixed spray to comeinto direct contact with a portion of the external surface of anincandescent heating element and cansing the steam to dissociate intohydrogen and oxygen and reaction between hydrogen and carbon.

Another object of this invention is to mount a plurality of said heatingelements in the gas-making generator and to cause said heating elementsto be successively moved into and out of the path of the mixed spray.

With the above and other objects in view the invention will behereinafter more particularly described, and the combination andarrangement of parts will be shown in the accompanying drawings andpointed out in the claims which form part of this specificat1on.

Reference will now be had to the drawings, wherein like numerals ofreference designate corresponding parts throughout the several views inwhich:

Figure 1 is a side view in elevation of my oil gas making unit, showingthe oil gas generator, first and second stage oil and water pumps, waterseal, scrubber, and gas bag or bellows; the oil gas generator, waterseal and scrubber being in section, the section being taken as on line2-2 in Figure 3, and the gas'bag being shown as partly broken away.

Figure 2 is a side elevation of the gas bag, partly broken away.

Figure 3 is a plan view showing the general arrangement of my oil gasmaking unit with the oil gas generator partly broken away to show themixed spray.

Figure 4 is an enlarged section of the second stage oil and water pumpsand shows an oil spraying diagram, the section being taken as on line 22in Figure 3.

Figure 5 is an enlarged sectional view of a diaphragm pump, one of whichis used as a first stage oil supply pump, and another of which is usedas a first stage water supply pump.

Figure 6 is a side view in elevation of the oil gas generator, partly inlongitudinal section along the shaft and shows a movably mounted heatingelement and the planetary mechanism for moving said element. The upperportion of the oil gas generator being partly broken away to show aportion of the heating grid.

In the drawings, reference character 10 indicates an oil gas generatorcomprising a gastight metal container 11, preferably of cylindricalshape and having covers or end plates 12, 12, through the center ofwhich passes a hollow shaft 13. Gas-tight packings 14, 14, at both endsof the shaft 13, prevent leakage of the gas around the shaft. On one endof shaft 13, there has been mounted a sprocket gear 15 driven by chain16 from a sprocket pinion 17 on the pump shaft 18, and causing shaft 13to revolve, as best shown 1n F1gure 3. The number of revolutions permlnute of the shaft 13 is equal to the number of strokes per minute ofthe differential second stage oil and water pump 19, divided by thenumber of heating elements used in the oil gas generator 10. In theembodiment shown, two elements 20, 20, are used and thus making thenumber of revolutions per minute of the shaft 13 one-half the number ofstrokes of the oil and water pump 19.

The oil gas generator 10 has on its upper top side 21 anextension trunk22 forming a receptacle on its inside for the waterdie. Jig grid 23. Theupper side 21 is pr vided with a flange 24 adapted to receive a waterseal or trap member 25 to which is fastened a scrubber or washer 26.

As best shown in Figure 1, a gas conduit 27 leads from the scrubber 26to a flexible gas bag or bellows 28; the functioning of this flexiblegas container being to store a small quantity of gas and being flexible*ill by its expansion and contraction operate the various time-o-statsor instruments controlling the operation of my self-contained oil gasgenerator as a whole, as described under operation.

A motor 29 is used for driving the mechanism of the oil gas generator10, said motor operating through a reducing gear 30, which eoaoae inturn operates the differential second stage oil and water pump 19, andalso the first stage oil supply pump 32, and the first stage watersupply pump 33. The whole apparatus being mounted on a suitablefoundation plate 34. Fixedly mounted on the shaft 13 in the oil gasgenerator 10 are disc-shaped members 35, 35, made of insulationmaterial. These disc-shaped members revolve with the shaft 13 in themanner of the arm of a planetary gear assembly.

On diametrically opposite points of the discs 35, 35, are pivot pins 36,36, of a heatresistlng metal, each pin being rotatably housed in abushing 37 fixed in the discs 35, 35. Planet pinion gears 38, 38, madeof insulating and heat resisting material are fastened to the pins 36,36, by means of nuts 39, 39.

The planet pinions 38, 38, engage centrally located stationary sun gears40, 40, made of insulation material, one sun gear being mounted at eachend of the oil gas generator 10, and secured by means of screws 41. 41.to the bearing arms 42, 42, fastened to the internal flanges 43, 43, ofthe container 11. by means of screws 44, 44. I l

The bearing arms 42, 42, extend diametrically and act as secondarybearings. allowing all the mechanism to be mounted and mechanicallyoperated and inspected while the cover plates 12, 12, are removed.

lVhile the pivot pin 36 is shown haviru no end play. pivot pin 36 can bemoved end W1S3 tl110llgl1 it bushing 37 so as to allow the heatingelements 20, 20, to be inserted between the pivot pins 36 and 36. and inthis way the heating e ements 20, 20, will revolve with the pins 36,being driven by the pinion gears 38, 38, wh1ch in turn are caused torevolve by engaging with the station arv sun gears 40, 46 and drivenaround said siin gears b tilge disc members 35, 35, fastener to theshaft Electric leads 45, are brought into the oil gas generator 10through the hollow shaft 13, from a contact plug 46, mounted at thesprocket end of shaft 13. The plu 46 revolves with the shaft 13. Theelectric leads 45, 45, pass through holes 46. 46, in the shaft 13, andare contacted to contact plates 4. and 47 secured to discs 35, 35, underbearmg shoulders 33, 31, of the pins 36 and 36. Contact plate 4.1 isformed to act as a sprin to provide a pressure against the end of Hi?)heating element 20, as best shown in Figure 6.

Electric current from the leads 45, 45" flows through the contact plates47 and 47 throu h screws 43, 48, through ring plates 49, 49, slecured tothe disk members and fur nishes a continuous supply of electric currentto any plurality of electrodes or heating elements 20, 20, which may bemounted be tween the discs 35, 35.

It will be seen that owing to the planet pinion 38, being of a smallerdiameter than the fixed sun gear 40, the electrodes 20, in revolvingwill present a different surface to the hydrocarbon oil spray and to thesteam at each revolution, as will be explained later under operation.

Each end of shaft 13 is plugged to make it gas-tight after the electricwires 45 and 45' have been inserted.

In the upper part of the container 11, is the coil or water heating grid23 made of piping which is supplied with water from the water pump 51,best shown in Figure 4, the object being that the hot gas from the oilgas generator 10, in passing on its way to the scrubber 26 will convertthe water in the grid 23 into steam, and at the same time assist incooling the gas.

The steam will pass through the hot grid piping 50, in a measured orregulated quantity and pressure to a row of orifices 52 in the lowestpipe 53 of the grid 23, as shown in Flgures 3 and 4. The pipe 53, havingthe orifices 52 is positioned inside the oil gas generator 10longitudinally across and adjacent to the oil spray 54 issuing from anozzle 55 so that the oil spray will pick up the steam jets 56, andcommingle with each other, and form a m xed spray 57 of oil and steambefore striklng the heating elements 20.

As best shown in Figure 3, the oil gas generator shaft 13 has a chaindrive sprocket 15 and cham 16 driven by sprocket 17. on the drive shaft18 of the differential second stage pump 19. As only two heatingelements are shown in the oil gas generator 10, this chain drive istherefore a two to one ratio. Shaft 18 of the differential pump 19 ismounted in s1de plates 59, 59, comprising brackets 66, 66, for securingto the foundation plate 34. The side plates 59, 59, are boltedto thepump body 60, which has a chamber 61 therein in which a cam 62 on shaft18 is adapted torotate, as best shown in Figure 4.

Cam 62, contacts with a roller 63, mounted on a pin 64; the roller 63and pin 64 being mounted in the enlarged portion 65' of the differentialplunger 65, 65.

The differential plunger 65, 65 is constructed with a small diameterfront end 65, reciprocating in a nose piece member 70, to act as secondstage oil pump 67, and with plunger 65' of larger diameter,reciprocating in pump body 60, to act as second stage water pump 51,both pumps being operated together on their delivery stroke by the cam62 and returned on intake stroke by a spring 68.

The small diameter front end 65 of the differential plunger 65, 65operates through packings 69 in a chamber 91, of the pump body 60. Pumpbody 60 has a flange 71 for securing the differential pump 19 to aflange 72 of the extension 73 of the oil gas generator 10.

- The nose piece member has a flange 74 secured between the flanges 71and 72. At the front end of the nose piece member 70, inside thegenerator extension 73 of the oil gas generator 10, is a thread 75, inwhich is screwed a retaining nut 76 of suitable form to retain inposition in the nose piece 70, a split atomizer nozzle shown in entiretyas 55, and consisting of two parts 77, 77. The nut 76 and split nozzle55 are brought up against soft metal washers 78, and 79, so that byexerting pressure with the nut 76, against a conlcal surface on theoutside of the split atomizer nozzle 55, the thickness of the fan-shapeoil spray can be changed. Tightening the nut 7 6 brings the parts 7 7,77 of the split nozzle 55 in closer relation with each other, and causesa finer oil spray. Within the split nozzle 55,

the front end 65 of the differential plunger 65, 65, reciprocates,thereby causing a pressure and discharging the oil in the form of anatomized mistlike spray of fan-shape form, as shown in Figure 3.

Oil is fed to the atomizer nozzle 55 through apertures 80, 81 and 82,from an inlet check valve 83, and a: regulating needle valve 84,attached to the pump body 60. The needle valve 84 is supplied with oilfrom the first stage oil supply diaphragm pump 32, through pipe 85, andthrough a delivery check valve 86, best shown in Figure 3.

In the differential second stage pump 19, shown in Figure 3, the shaft18ends in a coupling 87 connecting it with the shaft 88 of the reducinggear 30. The reducing gear is driven by shaft 89 through coupling 90 andmotor 29. haft 88 of the reducing gear 30 is extended into a casing 92adapted to house a cam 93.

As shown in Figure 5, the cam 93 actuates twobell cranks94,94. Bellcrank94 operates the first stage oil supply pump 32, through links 95. Theoil pump 32 gets its supply of oil through inlet check valve 96, andthrough regulating valve 97. Bell crank 94 operates the first stagewater supply pump 33, in the same manner, getting its supply of Waterthrough inlet check valve 96 and regulating valve 98, and deliveringthrough check valve 86 to water line 99, shown in Figure 3. V

The construction of the first stage oil and water diaphragm pumps 32 and33, is best shown on Figure 5, which shows a diaphragm 100, a glassvacuum reservoir 101, a strainer 102, inlet 103, and delivery 104.

The first stage oil and water pumps 32, and 33, used in combination withthe other apparatus, are duplicates of a preferred type of pump. It willbe understood, however, that other types of pumps could be used for thefirst stage delivery of oil and water.

As best shown in Figure 1, the water seal member 25, is bolted to thetop flange 24, of

the oil gas generator and has a passage 105, through which the gaspasses into a water seal bend 106, contained therein. An overflowconnection 107, has been provided on one side of the water seal member25, to allow overflowing into a U-shaped pipe 108. An internal flange134, has been provided to carry a perforated plate 109, acting as asupport for the scrubber medium 110. The scrubber 26, has its flange111, bolted to the flange 112, of the water seal member 25. The scrubber26, is provided at its upper end with a cover plate 113, to which issecured an outlet pipe 114:, connected to the gas conduit 27, and aninletpipe 115, to admit water to a spray ring 116, which sprays on aperforated plate 117, so that water is distributed over the entirecross-section of the scrubber. Vfater is supplied to the scrubber 26,from the dia phragm pump through a pipe 99, and regulating valve 118.

In the pipe 99, best shown in Figure 3, is a T-fitting 119, distributingsome of the water from the diaphragm pump 33, through a pipe 120,through inlet check valve 121, and regulating valve 122, to the secondstage water pump 51. The water from the pump 51, being delivered througha check valve 123, through a pipe 124, and a regulating valve 125, tothe water heating grid 23, in the upper part of the oil gas generator10.

The gas bag or bellows 28, comprises outer retaining casings 126, and126', a flexible bag 127, of suitable gas-tight material and having aninlet 128, and outlet 129. At the center of the bag where the expansionand contraction is most effective, there has been provided a rod 130,having a spring 131, fastened there to and being connected at its freeend to a suitable pressure switch 132, which controls the supply ofelectric current for starting and stopping the gas-making unit as awhole. A threaded handwheel 133, against which the spring 131, reacts,serves for setting the pres- 7 sure at which the gas bag or bellows 28,will operate the pressure switch 132.

It is to be noted that the nozzle 55, is split in an axial direction soas to form a ribbonlike slot or orifice 136, between the two nozzleparts 77, and 77, and that the nozzle is of the constantly-open type.The nozzle is positioned at the discharge end of the pump 67, so thatthe front end of the diiferential plunger 65. is central with andreciprocates in the nozzle. The axis of the nozzle is tangent to theperiphery of rotation of the heating elements.

The operation of the oil gas making unit as a whole is as follows: Thegas bag 28, when empty, will be collapsed, thereby operating thepressure switch 132, so as to cause a continuous supply of electriccurrent to flow through the lead 45, through the heating elements 20,20, bringing them to a pre-determined temperature, also heating thegas-tight and air-tight oil gas generating chamber 11. WVhen the desiredtemperature has been reached in the chamber 11, the thermo-switch 135will contact and cause an electric current to flow through the motor 29,and start it up. The motor 29 will drive through the reduction gear 30,the oil pump 32, and water pump 33, delivering the oil and water to thedifferential second stage or measuring pump 19.

he pumps 51 and 67, as well as the heating elements 20, 20, in the oilgas generator 10, are driven by the same mechanism from the motor 29,and will function as follows: Pump 51 will deliver a measured quantityof water intermittently to the heating grid 23, where it will be flashedinto steam and forced out of the orifices 52 in the lowest pipe 53, ateach stroke of said pump, as best shown in Figure 4.

Pump 67, will simultaneously deliver a measured quantity of oilintermittently through the axially split nozzle 55 through a ribbon-likeslot or orifice 136, between the two parts 77, 7 7 of the nozzle, andforming an atomized fan-shaped oil spray 5 1. The quantity of oildelivered into the oil gas generator 10 by the pump 67 is regulated bythe valve 84. The quantity of water delivered to the oil gas generator10 by the pump 51 is regulated by the valve 122. The first stage pumps32 and 33 both automatically cut out if overloaded either by excesspressure or excess quantity of liquid taken in, under which conditionsthe toggle links 95 collapse and cause the diaphragm 100 to stoppulsing, as best shown in Fig. 5.

The oil spray 54 will commingle with the steam jets 56 from the orifices52, and together as mixed spray 57, come in contact with the heatingelements 20 and cause the steam to dissociate. It being understood thatthe heating elements 20 are geared to revolve around the axis of thegenerator and so timed as to synchronize with the intermittent strokesof the differential pump 19, and to cause one of said elements to passthrough the line of mixed spray 57 during the delivery stroke of saiddifferential pump.

Furthermore, each heating element 20 is being rotated on its own axis soas to present a different portion of its heated surface to the line ofmixed spray 57 during each revolution. As the spray 57 comes in contactwith a heating element 20, when it is in an incandescent state, thesteam will be dissociated and gas will commence to form immediately andcontinue to be given off while the elements continue in their circularpath.

The gas after being given off from the heating elements will pass out ofthe generator by volume, and may be impelled on its way by revolvingvanes 137, shown in Figure 1.

Hot gas passing over the external surfaces of the grid 23 will cause thewater in the grid to be heated. The gas will pass through the gaspassage 10501 the trap or seal member 25 and thence through the sealpipe 106, one end of which is secured by flange 138 to the seal member25, and the other end remaining open, but extending below the waterlevel indicated by N. L. The oil gas will then rise through the scrubber26 meeting the wash water spray descending through scrubber medium 110from spray ring ll6, then will pass out through outlet pipe 11% andconduit 27 to the gas bag'or bellows 28. This bag 28 will become eX-panded as it fills with gas and will operate the switches and cut oilthe entiresupply of electric current, both to the heating elements 20and to the motor 29, thereby stopping the gas making, but leaving theswitches in such a condition that when the gas bag 28 collapses thecurrent will again be caused to flow and the gas making automaticallystarted again. The gas bag 28 from its outlet 129 can be connected toany size gas container, which on being filled or emptied will act on thegas bag 28, in combination, to start and stop the gas plant. It will beunderstood, however, that when the bag 28 collapses and throws in thepressure switch 132, sending current into the heating or resistanceelements 20, 20, that the mot-or 29, pump 19, and the driving 11echanism for the said elements will not commence to operate until theheat in the generator has reached the predetermined temperature at whichthe thermoswitch 135 is set. .011 reaching this temperature, thethermo-sw1tch135 Wlll start the motor and the driving mechanism. Inother Words, the pressure switch 132 can cut on? the entire electriccurrent supply, but cannot start the motor 29 without the cooperation ofthe thermo-switch 135.

It is to be noted that during themovement of aheating element 20, in thecircular path 139, that, when the element commences to pass through theline of mixed spray 57, gas commences to form and continues to be givenoff for a distance after leaving the line of mixed spray, or through azone 1&0, as best shown on diagram, in Figure 4. During the remainderor" the travel in the circular path 139, the heating element passes nearthe pipes in the heating grid 23, and turns the water in said grid intosteam.
